ISH: Neues im Bad! Bath Design 2009 - Form

Wenn die Balgzylinder mit Druckluft
gefüllt werden, dehnen sie sich
aus und heben so den 200 Kilogramm
schweren Pool an. Seitliche
Führungsrollen gleichen Höhenunterschiede
bei unterschiedlicher
Dehnung der Bälge aus.
When the bellows cylinders are filled
with compressed air they expand and
in so doing elevate the pool, which
weighs 200 kilograms. Guide rollers
on the sides of the frame compensate
for differences in height where the
bellows expand unequally.
überschwappenden Wassermengen locker aufnehmen
kann. Die deutsche DIN-Norm 19643 erlaubt
eine Spaltbreite bis zu 50 Millimeter, Schmidt wollte
sie so schmal wie möglich haben. Also mussten Versuche
unter Realbedingungen im Labor von Hoesch
Klarheit bringen. Das Ergebnis: eine Überlaufrinne
mit 35 Millimeter Spaltbreite, in der sich auch noch
Platz für ein Panel mit Schwallwassereinlauf, Bedienfeld,
Lautsprecherboxen und Frischwasser-Regenbrausen
befindet.
Mit den Whirlpools kann Hoesch auch seine
Kompetenz im Tiefziehen demonstrieren. Die Pools
werden inklusive Überlaufrinne aus einem Stück
Polymethylmethacryl at tiefgezogen. Es gibt auch
eine rechteckige Version für bis zu fünf Personen:
3600 mal 2600 Millimeter exklusive Rinne aus einem
Stück tiefgezogen sind eine Herausforderung.
Until now a whirlpool was a fixed tub intended for
use inside or outdoors. Now Michael Schmidt from
Code 2 Design has given the bubbling tub a fresh
interpretation. His creation for Hoesch Design is a
piece of furniture on castors you can wheel onto
the patio when the sun comes out. We let you in on
the design process.
Not only secret agents like James Bond relax in whirlpools.
Also known as hot tub or Jacuzzi the tub, whose
powerful jets of water and compressed air massage the
skin, can be found in swimming pools, fitness clubs,
hotel s and cruise ships – and also increasingly in pri -
vate households. Düren-based Hoesch Design AG and
Micha el Schmidt from the Stuttgart studio Code 2
Desig n are showcasing a whirlpool on wheels at the ISH.
When empty you can push it from the bathroom onto
the patio in the summer. “The portable whirlpool can be
used all year around, outside in the summer, and in the
house when it is cold and rainy. The same goes for hotels
and the like, who cannot afford or do not want two
different types of tub,” argues Hoesch Sales Director
Klaus Marschall. “The pool being portable was not even
part of the brief,” says Schmidt. In his first sketches he
had given the pool an awning because he personally prefers
to bathe outdoors, as he did while on vacation in
South-East Asia. He presented the sketch to Hoesch
Technical Director Jürgen Magin, who responded spontaneously
saying: “It must have wheels” – well aware
that a full whirlpool can weigh a good 1,200 kilos. However,
without water, i.e., a ton lighter, it seemed feasible.
Schmidt got in touch with Festo AG in Esslingen. They
recommended their bellows cylinders, which compared
with pneumatic, mechanically operated cylinders are relatively
hard wearing. The bellows expand like a tube that
you pump air into, and the pool is lifted. That said, a bellows
cylinder fills faster, which means the support frame
has to remain flexible. The solution was support rollers
on the side walls. The similar principle is used in floating
piers that are attached to pylons via rollers like the ones
Schmidt had seen in Thailand. The patent Code 2 Design
and Hoesch apply for will probably be for “portability of
large water containers” and have a wide range of applications.
Schmidt’s original idea was a circular pool. The
result was a pool, whose overall shape is asymmetrical.
Simultaneously, the pool was to look like a piece of furniture,
appear more delicate. The interiors of existing
Jacuzzi s are shaped like the human body and consequently
dictate how occupants can lie or sit in them.
Im Versuchslabor von Hoesch (unten):
Wer in den vollen Pool steigt,
verdrängt etwa 50 Liter Wasser,
die die Überlaufrinne aufnehmen
können muss. Die roten Linien im
CAD-Rendering markieren Radien
und Flächenübergänge für den
italienische n Werkzeughersteller.
In the Hoesch test lab (below): When
someone enters the pool when it is
full they displace about 50 liters of
water, which the overflow channel
must be able to accommodate. The
red lines on the CAD rendering
mark radii and surface transitions
for the Italian tool manufacturer.
Die extrem asymmetrische Wannenform
auf dieser frühen Skizze
korrigierten die Designer später
wieder – zugunsten einer optimalen
Bewegungsfreiheit im Jacuzzi.
The designers corrected the extremely
asymmetrical shape of the tub in
this early sketch later on – in favor
of optimum freedom of movement
in the whirlpool.
